I'm using an AI AE mk1 for FTR (just starting) and was wondering about saving weight (on the rifle as I'm F**KED!!

Question 2 - I'd like to lighten the trigger a little more as I have been spoiled with my 1 1/2 OZ trigger pull on .22 benchrest gun and keep getting what I would call false pulls - that is to say, when ready to fire, I squeeze and find ... I've to squeeze further ... I've lightened the trigger a far as I dare to ... but still a little too heavy ... no I don't want a 1 1/2 oz, but a little lighter than it is now... options please...
Thanks
